STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 467,998, dated February2, 1892.

Application filed January 18,1890. Renewed July 16, 1891- Serial llor399,680- (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. SHERIDAN, a citizen of the United States,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented certain new and useful Improvements in Stem\Vinding and Setting Watches, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to that class of stemwinding and stem-settingwatches provided with stem-driven trains connected with the winding andhands-setting or dial wheels.

The principal object of my invention is to provide a simply-constructedwatch -movement of the class referred to, in which the gear-wheelforming part of the connection between the stem-driven pinion and thewinding-wheels is carried by an oscillating yoke, and in which thegear-wheel forming part of the connection between the stem-driven pinionand the dial-wheels is entirely disconnected from said yoke, so thatoscillating movements of the latter have no effect whatever upon it.

My invention has also for its object to provide means of simpleconstruction whereby when the movementis out ofthe case engagement ofthe stem-driven train either with the winding or hands-setting or dialwheels may be effected, the construction being such that the parts willstay in either of the engagements desired when placed in such engagement.

In the accompanying drawings, Figure 1 is a plan or face view of awatch-movement embodying my invention and with the parts in position forconnecting the pendant arbor with the mainspring-arbor. Fig. 2 is asimilar view, but with the mechanism in position to engage thependant-arbor with the dialwheels. Fig. 3 is asection on line 00 a: ofFig. 1; and Fig. 4, a section on line-m as, Fig. 2. Fig. 5 is a reverseside View from that shown. in Fig. 1. Fig. (5 is a detail view of theslid ing bar, the lever for lifting the same, and some adjacent parts.Fig. 7 is apartial sectional view of the-pillar-plate, showing some ofthe parts mounted thereon. I

A denotes the center band of a watch-case provided with a pendant a, andB is the pilsaid winding-wheel.

lar-plate of a watch-movement, said plate being fitted to and secured tosaid band in the usual manner.

Within the pendant (t is the stem-arbor a, provided with the usualcorrugated cap at its outer end. The inner end of the said arbor isengaged axially with the stem of a pinion C, journaled in suitablebearings 011 the lower side of the pillar-plate B, and having a toothedperiphery extending through an opening 0 of said plate. Suitably pivotedto the pillarplate is a gear-wheel c, withwhich the pinion O is inengagement.

E denotes a pivoted yoke attached to the pillar-plate by a screw c and acap 0 said yoke being provided at one end with a pin 6, passing throughan opening bin the pillarplate, and on which pin on the upper or faceside of the pillar-plate and on the lower or rear side of the yoke E isjournaled a gearwheel 6, adapted to be thrown into engagement with thewinding-wheel F of the mainspring-arborf. Thus when the said yoke ismoved to the positions shown-in Figs. 1 and 2, the wheel 6' may bethrown into engagement with or be disengaged from the winding-wheel F,the spring N, engaging said yoke, normally holding the said wheel a inengagement with G denotes a sliding bar provided with an arm g, enteringan axial recess in the pinion G, which forms a bearing for said bar tosteady it in its rectilinear movements, the arm 9 of the said slidingbar being provided with a'beveled portion g and the said bar having nearits center a pin 1 K is a bell-crank lever, the upper or longer arm ofwhich is in engagement with the pin g of the sliding bar G and the loweror shorter arm of which is provided with a pin 10 en- I gaged by thefree end of a spring L, pivot-' ally attached at Zto the pillar-plate B,and provided with a pin Z, which is engaged by a screw M, tapped to theedge of the pillarplate. a

The pillar-plate is provided with a pin 19*, on which is journaled asliding or shifting gearwheel (2 provided with a grooved hub engaged bythe free forked end of a spring e attached to the pillar-plate andnormally tending to press the said shifting gear-wheel ICO inward towardthe bottom of the recess in the pillar-plate in which it is located.

I is a sliding pin the head of which is beneath the spring e said pinpassing through the pillar-plate and being provided with a beveled orrounded projecting end adapted to be engaged by the beveled portion 9 ofthe arm g to force the said pin against the said spring 6 thereby movingthe shifting gearwheel from the position shown in Fig. 3, in which it isin engagement only with the gearwheel 0', into the position shown inFig. 4, in which it will be in engagement both with the gear-wheel c andwith the setting-wheel II, forming part of the dial-train.

The operation of my invention is as follows: When the stem-arbor ispressed inward to its limit, the sliding bar G will be depressed, sothat it is disengaged from the pin e, carried by the pivotedyoke E,thereby permitting the spring N to, hold said yoke in such position thatthe gear-wheel e is in engagement with the winding-wheel F. I11 thisdepressed position of the sliding bar G its beveled portion g isdisengaged from the end of the pin I, projecting throughthepillar-plate, as shown in Figs. 3 and 7, thereby permitting thespring a to hold the wheel 6 out of engagement with the dial-wheel H.When the stem-arbor is lifted or pulled outward to its limit, the springL, pressing 011 the pin carried by the bellcrank lever. K, turns saidlever on its pivot, causing its arm 71?, which is in engagement withthepin '9 on the sliding bar G, to lift the said sliding bar intoengagement with the pin e, carriedby the pivoted yoke E, thereby turningthe said yoke on its pivot, so as to remove the wheel 6 from engagementwith the winding-wheel F. As the said sliding bar is lifted, itsbeveledportion g engages the projecting end'ofthe pin I, thusmoving saidpin andthe spring e with which it is in contact to'the position shown inFig. 4:, thereby shifting the wheel e on its pin 11 into position toengage the dial-wheel H, the said wheel 2 being, it will be understood,also in gear with the wheel 0', which is in mesh with the pinion C, sothat the movement of the stem-arbor may now be transmitted to thedial-wheels for the purpose of setting the hands. hen the movement isout of the case, the screw M, when in its innermost position inengagement with the. pin Z, carried by the pivoted spring L, gives thesaid spring a suitable tension to cause the sliding bar G to be liftedand the stem-driven train to be held in connection withthe dial-wheels;but when the said screw is withdrawn from engagement with the said pin Zor is removed from the pillar-plate B it relieves the tension of saidspring, and the stem-driven train is then allowed to connect with thewinding-wheel through the action of the spring N, as hereinbeforedescribed. I thus provide means whereby a stem-driven train comprising agear-wheel which is en tirely disconnected from a pivotal yoke may beconnected either with the winding-wheels or dial-wheels both when themovement is in the case and when it is removed therefrom.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. In a stem winding and setting watch, the combination,with a stem-arbor and a pinion driven thereby, of winding and settingstemdriven trains, a pivoted yoke carrying a gearwheel forming part ofthe winding-train, a shifting gear-wheel forming part of thesetting-train and operated independently of said yoke, a sliding baroperated by the stem-arbor, a spring normally holding said shiftinggearwheel disengaged from the other wheels of the setting-train, andsuitable connections whereby said sliding bar is caused to vibrate saidyoke to disconnect the winding-train and to force said. shiftinggear-wheel positively into operative connection with the setting or dialwheels.

2. In a stem winding and setting watch, the combination, with astem-arbor and apinion operated thereby, of stem-driven winding andsetting trains, a shifting gear-wheel forming part of the setting-train,and a sliding bar having a portion directly engaged by said stem-arborand having another portion serving to actuate said shifting-wheel andforce it positively into operative connection with the setting or dialwheels.
